Specification of Letters Patent.

Patented Dec. 12, 1905.

Application filed August 16, 1905. Serial No. 274,431.

To all whmn it may concern:

Be it known that I, HOLLES A. MOQUILLIN, a citizen of the United States,residing at Wau seon, in the county of Fulton and State of Ohio, haveinvented a new and useful Colter Attachment for Plows, of which thefollowing'is a specification.

This invention relates to plows, and has for its object to improve theconstruction and increase the efiiciency of the supporting and adjustingmechanism of the disk-jointer or colter devices of implements of thischaracter.

Another object of the invention is to provide asimply-constructed andeasily-applied device whereby the disk cutter may be adjusted in alldirections relative to the beam or moldboard and firmly supported in anyof its adjusted positions.

With these and other objects in view, which will appear as the nature ofthe invention is better understood, the same consists in certain novelfeatures of construction, as hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, andin which corresponding parts are denoted by like designatingcharacters,is illustrated the preferred form or embodiment of theinvention capable of carrying the same into practical operation.

In the drawings, Figure 1 is a side elevation, and Fig. 2 is a'planview, of a plow with the improvement applied. Fig. 3 is an enlargedsectional detail of the improved device detached, and Fig. 4 is asectional detail of the beam-clamp portion of the device.

The improved device may be attached to any of the various forms ofplow-beams in use and operative with any of the various sizes and formsof moldboards, but for the purpose of illustration is shown applied toan ordinary steel beam-plow in which the beam 10, moldboard 11, andshare 12 are of the usual form.

The improved device herein shown and described consists of a standard13, threaded at the upper end and with an intermediate offset 15, asshown. Bearing above and below the beam 10 are two rods 16 17 havingeyes 18 19 at one end for receiving the standard 13 and with theopposite ends threaded and carrying nuts 20 21, supportinga clamp-plate22 against the opposite side of the beam, the standard 13 being thusfirmly clamped adjustably to the beam. The threaded end of the standardis provided with a clamp-nut 23, bearing upon the upper eye 18 of therod 16 and firmly supporting the standard from downward movement, whileat the same time permitting vertical adjustment thereto. EXtendinglaterally of the lower part of the standard 13 is an arm 24, threaded atone end, as at 25, and forked at the opposite end, as at 26 27 theforked portions with threaded terminals, as at 28 29. A lateral shoulderor collar 30 is arranged upon the member 24 between the forked portionand the body of the member. The forked portions 26 27 embrace the mainstandard 13, and the latter is clamped in position between the forks bya clamp-plate 31 and clamp-nuts 32 33, as shown in Fig. 3. The standardis thus firmly compressed into the wedge-shaped cavity between theforked portions and rigidly coupled in place, while at the same time thearm is readily adjusted in position upon the standard when required.

The cutting-disk 34, in dishing form, as

shown, is rotatively mounted upon the arm 24 and bears against theshoulder 30 and is clamped in position by binding-nuts 35 36 upon thethreaded end 25 of the arm. Rotative upon the arm 24, between the nuts35 36, is a scraper-standard 37 the nuts thus serving the twofoldpurpose of means for holding the cutter-disk and the scraper-standard inplace.

'Rotatively adjustable upon the standard 37 is a scraper-blade 38,preferably formed by bending a sheet of metal around the standard andsecuring in place by a clamp-screw 39. The free end of the plate 38 issharpened and bears against the inner face of the cutter member 34 andremoves all adhering earth or other material therefrom as the cutterrotates against the scraper. The standard member 37 and scraper 38 arethus adjustable relative to the cutter-disk, so that the scraper may beadjusted to perform the required action in a satisfactory manner.

The parts are simple in construction, can be readily applied to theplow, and adjusted to any required extent.

Having thus described the invention, what is claimed is 1. In a plow,astandard depending from the beam, an arm extending transversely of saidstandard and carrying a cutting-disk at one end and with the other endforked to embrace the standard and with forked portions of the armthreaded, a clamp-plate carried by said threaded portions and bearingagainst said standard and clamp nuts carried by said threaded portionand bearing against said plate.

2. In aplow, a standard depending from the beam, an arm extendingtransversely of said standard, and with a lateral shoulder intermediatethe ends and with one end threaded and the other end forked forembracing said standard, the terminals of the forked portions beinglikewise threaded, a clamp-plate carried by said forked portions andbearing against said standard, clamp nuts carried by said forkedportions and bearing against said plate, a cutting-disk carried by saidarm and bearing against said shoulder, and clamp-nuts upon the arm inadvance of the disk and bearing upon the same.

3. In a plow, a standard depending from the beam, an arm extendingtransversely of said standard means for adjustably coupling said arm tosaid standard, a cutting-disk mounted for rotation upon said arm, astandard carried by said arm and bearing upon the disk-supportingmembers, a scraper adjustably connected to said arm-standard andengagingsaid disk-supporting members, and aclamp-nut operating upon said arm andbearing upon said arm-standard.

4:. In a plow the combination of a draftbeam, a vertical standard havingthe upper end threaded and extending above and below the draft-beam,rods having eyes at one end for engaging said standard above and belowthe draft-beam and with the opposite ends threaded, a clamp-plateengaging said rods and bearing upon the opposite side of the draft-beam,clamp-nuts operating on said rods and bearing upon said plate, and aclamp-nut upon said standard and bearing upon the adjacent rod.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two Witnesses.
